Maya Hair Card Uv problem

Isiktor

I am trying to make Hair cards like this http://www.3dartistonline.com/news/2015/04/how-do-i-create-real-time-hair-for-games/

And I make it to step 8 and then when I try to make the UVs follow that step I get this problem 
I get this right after I unfold the UV, also I just saw that when I move and sew the UVs mine just 
fills up the UV . 

I have no idea what is happening and I have looked around for a few days trying to find out. 

Any ideas or suggestions would be great 
Thanks

If move and sew is doing nothing, then your verts probably aren't welded in the mesh. So do that then try again. Also, it's helpful when you do go from unitize to move/sew to scale that big uv square down first.
super late edit: I forgot that adjacent faces can be welded but have inverted normals, which move&sew will refuse to do. Mesh Display>Conform to fix that.
